a balloon has the volume of 90 L at a pressure of 45 kPa. What will the volume be if the pressure increases 135 kPa.
P1V1 = P2V2
can you do it foe mee?
All you need to do is to substitute and punch your calculator. If you don't feel comfortable doing that you need to practice more. Good luck!
To determine the volume of the balloon when the pressure increases, you can use Boyle's Law. Boyle's Law states that the volume of a gas is inversely proportional to its pressure when temperature is constant.
The formula for Boyle's Law is:
P1 * V1 = P2 * V2
Where:
P1 is the initial pressure (45 kPa)
V1 is the initial volume (90 L)
P2 is the final pressure (45 kPa + 135 kPa = 180 kPa)
V2 is the final volume (which we want to find).
We can rearrange the formula to solve for V2:
V2 = (P1 * V1) / P2
Now we can substitute the given values into the formula:
V2 = (45 kPa * 90 L) / 180 kPa
Let's simplify the expression:
V2 = (4050 kPa·L) / 180 kPa
Now, cancel out the units and calculate:
V2 = 22.5 L
Therefore, when the pressure increases by 135 kPa, the volume of the balloon will be 22.5 L.
